Abstract
More than 100 years have passed since the first lectin ricin was discovered. Since then, a wide variety of lectins (lect means "select" in Latin) have been isolated from plants, animals, fungi, bacteria, as well as viruses, and their structures and properties have been characterized. At present, as many as 48 protein scaffolds have been identified as functional lectins from the viewpoint of three-dimensional structures as described in this chapter. In this chapter, representative 53 lectins are selected, and their major properties that include hemagglutinating activity, mitogen activity, blood group specificity, molecular weight, metal requirement, and sugar specificities are summarized as a comprehensive table. The list will provide a practically useful, comprehensive list for not only experienced lectin users but also many other non-expert researchers, who are not familiar to lectins and, therefore, have no access to advanced lectin biotechnologies described in other chapters.

Abstract
Fungi are members of a large group of eukaryotic organisms that include yeasts and molds, as well as the most familiar member, mushrooms. Fungal lectins with unique specificity and structures have been discovered. In general, fungal lectins are classified into specific families based on their amino acid sequences and three-dimensional structures. In this chapter, we provide an overview of the approximately 80 types of mushroom and fungal lectins that have been isolated and studied to date. In particular, we have focused on ten fungal lectins (Agaricus bisporus, Agrocybe cylindracea, Aleuria aurantia, Aspergillus oryzae, Clitocybe nebularis, Marasmius oreades, Psathyrella velutina, Rhizopus stolonifer, Pholiota squarrosa, Polyporus squamosus), many of which are commercially available and their properties, sugar-binding specificities, structural grouping into families, and applications for biological research being described. The sialic acid-specific lectins (Agrocybe cylindracea and Polyporus squamosus) and fucose-specific lectins (Aleuria aurantia, Aspergillus oryzae, Rhizopus stolonifer, and Pholiota squarrosa) each showed potential for use in identifying sialic acid glycoconjugates and fucose glycoconjugates. Although not much is currently known about fungal lectins compared to animal and plant lectins, the knowledge accumulated thus far shows great promise for several applications in the fields of taxonomy, biomedicine, and molecular and cellular biology.

Cancers (Basel) 2011; 3:4151-69.

Abstract
Among the most challenging of clinical targets for cancer immunotherapy are Tumor Associated Carbohydrate Antigens (TACAs). To augment immune responses to TACA we are developing carbohydrate mimetic peptides (CMPs) that are sufficiently potent to activate broad-spectrum anti-tumor reactivity. However, the activation of immune responses against terminal mono- and disaccharide constituents of TACA raises concerns regarding the balance between “tumor destruction” and “tissue damage”, as mono- and disaccharides are also expressed on normal tissue. To support the development of CMPs for clinical trial testing, we demonstrate in preclinical safety assessment studies in mice that vaccination with CMPs can enhance responses to TACAs without mediating tissue damage to normal cells expressing TACA. BALB/c mice were immunized with CMPs that mimic TACAs reactive with Griffonia simplicifolia lectin 1 (GS-I), and tissue reactivity of serum antibodies were compared with the tissue staining profile of GS-I. Tissues from CMP immunized mice were analyzed using hematoxylin and eosin stain, and Luxol-fast blue staining for myelination. Western blots of membranes from murine mammary 4T1 cells, syngeneic with BALB/c mice, were also compared using GS-I, immunized serum antibodies, and naive serum antibodies. CMP immunization enhanced glycan reactivities with no evidence of pathological autoimmunity in any immunized mice demonstrating that tissue damage is not an inevitable consequence of TACA reactive responses.

Abstract
BACKGROUND αGal-specific lectins, monoclonal and polyclonal antibodies (Abs) are widely used in xenotransplantation research. Immunological assays such as immunohistochemistry, flow cytometry, Western blot and thin layer chromatography are often the only applicable characterization procedures when limited amount of tissue is available and biochemical characterization is impossible. Hence, detailed knowledge of the Ab/lectin carbohydrate-binding specificity is essential. METHODS The binding specificity of human blood group AB serum, three different affinity-purified human polyclonal anti-Gal Ab batches, and two anti-Gal mAb clones (TH5 and 15.101) as well as Griffonia simplicifolia isolectin B4 and Marasmius oreades agglutinin were examined for reactivity with glycolipid fractions isolated from human and pig (wild-type and α1,3GalT-KO) tissues using thin layer chromatogram and microtiter well binding assays. RESULTS All anti-Gal-specific reagents reacted with the pentaglycosylceramide Galα1,3nLc4, and several 6-12 sugar compounds in wild-type pig kidneys. However, their staining intensity with different αGal antigens varied considerably. Some, but not all, anti-Gal reagents cross-reacted with a pure iGb3 glycolipid reference compound. No reactivity with glycolipids isolated from α1,3GalT-KO pig small intestine or human tissues was found, confirming the specificity of the anti-Gal reagents in those tissues for α1,3Gal-epitopes produced by the α1,3GalT (GGTA1). CONCLUSIONS Different anti-Gal reagents vary in their carbohydrate epitope specificity. Mono-/polyclonal Abs and lectins have different carbohydrate epitope fine specificity toward pig glycolipids as well as purified Galα1,3nLc4, and iGb3. Despite the difference in αGal specificity, all reagents were completely non-reactive with glycolipids isolated from α1,3GalT-KO pig small intestine.

Abstract
Transplantation of organs across species (xenotransplantation) is being considered to overcome the shortage of human donor organs. However, unmodified pig organs undergo an antibody-mediated hyperacute rejection that is brought about by the presence of natural antibodies to Galalpha(1,3)Gal, which is the major carbohydrate xenoantigen. Genetic modification of pig organs to remove most of the Galalpha(1,3)Gal epitopes has been achieved, but the human immune system may still recognize residual lipid-linked Galalpha(1,3)Gal carbohydrates, new (cryptic) carbohydrates or additional non-Galalpha(1,3)Gal carbohydrate xenoantigens. The structural basis for lectin and antibody recognition of Galalpha(1,3)Gal carbohydrates is starting to be understood and is discussed in this review. Antibody binding to Galalpha(1,3)Gal carbohydrates is predicted to primarily involve end-on insertion of the terminal alphaGal residue, but it is possible that groove-type binding can occur, as for some lectins. It is likely that similar antibody and lectin recognition will occur with other non-Galalpha(1,3)Gal xenoantigens, which potentially represent new barriers for pig-to-human xenotransplantation.

Abstract
Cell surface carbohydrates present on BG01 human embryonic stem cells after 28 days of differentiation were examined using two classes of carbohydrate binding proteins: lectins and antibodies specific for carbohydrate epitopes. Specificity of lectin staining was verified using carbohydrate ligands to block lectin interaction, glycohydrolases to cleave specific sugar residues that are receptors for these proteins, and periodate oxidation to destroy susceptible sugar residues. Specific antibodies were used to identify various tissue types and germ layers present in the 12- and 28-day differentiating embryoid bodies. Results from 12 and 28-day differentiated embryoid bodies were compared to determine changes over time. A slight increase in the sialylation of alpha-GalNAc was seen between 12 and 28 days of differentiation due to the presence of sialyl Tn and/or other sialylated alpha-GalNAc residues. Increases were also observed in GalNAc, the T antigen (Gal beta1,3 GalNAc), and difucosylated LacNAc residues during this time interval. Additionally, some distinct differences in the pattern of lectin staining between 12 and 28 days were observed. Not unexpectedly, the presence of most differentiated cell-types increased during this time period with the exception of neural progenitors, which decreased. Undifferentiated cells, which were prevalent in the 12-day EBs, were undetectable after 28 days. We conclude that several changes in glycosylation occurred during the differentiation of embryonic stem cells, and that these changes may play a role in embryonic development.

Abstract
Development of invariant natural killer T (iNKT) cells requires the presentation of lipid ligand(s) by CD1d molecules in the thymus. The glycosphingolipid (GSL) isoglobotrihexosylceramide (iGb3) has been proposed as the natural iNKT cell-selecting ligand in the thymus and to be involved in peripheral activation of iNKT cells by dendritic cells (DCs). However, there is no direct biochemical evidence for the presence of iGb3 in mouse or human thymus or DCs. Using a highly sensitive HPLC assay, the only tissue where iGb3 could be detected in mouse was the dorsal root ganglion (DRG). iGb3 was not detected in other mouse or any human tissues analyzed, including thymus and DCs. Even in mutant mice that store isoglobo-series GSLs in the DRG, we were still unable to detect these GSLs in the thymus. iGb3 is therefore unlikely to be a physiologically relevant iNKT cell-selecting ligand in mouse and humans. A detailed study is now warranted to better understand the nature of iNKT cell-selecting ligand(s) in vivo.

Abstract
The specificity and binding capacity of the galactophilic lectin from the Gram negative bacterium Pseudomonas aeruginosa (PA-IL) was determined by solid phase measurements using galactosylated neoglycoproteins immobilized on microtiter plates. The bacterial lectin reacted with both short chain (monosaccharide) and long chain (pentasaccharide) glycoconjugates. Among the Galalpha1-XGal disaccharides, the highest affinity was observed towards the Galalpha1-3Gal structure. Raising the incubation temperature enhanced the lectin-polysaccharide agglutination, and it is suggested that binding to certain conformations of polysaccharides could vary between lectins with the same monocarbohydrate specificity and that this activity may, in part, be temperature dependent. Histochemical examination of lectin binding to different porcine tissues suggests a differential glycosylation of the carbohydrate antigens on endothelial cells in various parts of the vascular system. In the pancreas, PA-IL also adhered to the excretory ducts. These observations on PA-IL binding could be of importance both to determine infection foci in P. aeruginosa-mediated vacuities and to determine its role for pancreatic involvement in cystic fibrosis.
